摘要:
An information reproducing medium comprises plural tracks for recording information arranged to form a band and such plural bands are arranged normal to the direction of the track arrangement. The track has no area for obtaining an information reproducing clock. In a reproducing method, when information on one track of one band is to be reproduced, an information reproducing clock is derived from at least a portion of information on a track other than the one track, preferably a track adjacent thereto.
